Specification of Letters Patent. Patented July 12, 191.0.

Application filed March 1 1, 1910. Serial No. 548,516.

To all whom it may concern:

l 3e it known that I, ARGYLE CAMPBELL, a citlzen of the United States,residing in Cl1icago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Hopper Dump-Cars, of which thefollowing is a specification.

My invention relates to improvements in hopper dump cars.

The object of my invention is to provide a hopper car with inside dump,which will be of astrong, simple, eflicient and durable construction,composed of few parts and capable of being'chcaply manufactured.

The invention consists in the means employed to accomplish this objector result as herein shown and described, and particularly specified inthe claims.

In the accompanying drawing forming a .part of this specification,Figure 1 is a plan view of my improved dumpcar, one-half the length ofthe car body being omitted to enable the construction to be shown on alarger scale and more distinctly. Fig. 2 is a side elevation. Fig. 3 isan end elevation, partly in cross section, on lines 33 and 3*--3 of Fig.2. Fig. 4 is an enlarged detail section on line 4:4 of Fig. 2 and Fig. 5is a detail side elevation looking in the direction of the arrow marked5 in Fig. 4. Fig. 6 is a detail plan view of the winding drum andconnecting links. 'Fig. 7 is a detail elevation of same and Fig. 8 is adetail front or edge view of same.

In the drawing, 1 represents the body of 'my dump car, 2 the uprightside sheets of the car body, secured to the upright posts or framemembers 3, 4 the'side" hopper sheets, 5, 6'the inclined end floorsheets, 7 central longitudinal inside hopper sheets and 8 the centersills of the car body.

The hopper bottom of the car body is 1 provided with a plurality of dooropenings 9, the same being separated at their ends by the transversehopper sheets 10 and closed by the doors 11, which are connected byhinges 12 at their upper inner edges 13 to the hinge butts or brackets14 which are secured to the center sills 81.

15 are the door operatingshafts, extending longitudinally of the car,one on each side and near the outer edge, thesame being journaled insuitable bearings on the brackets 16, which are secured to and below theside hopper sheets 4. Each of the operating locking shoulder 22, and oneof the connecting links, preferably the middle one, is also providedwith a corres onding and 006perating shouldered locking face 23. Thelink 21, which is pivoted at one end to the door, is preferablyfurnished with a right angle bend 24:, so that the short link 20, whichis provided'with a locking shoulder or face 23, may engage-the drum whenthe door is closed centrally and directly opposite the axis of theoperatingshaft. The operating shaft 15 is provided with a ratchet 25,the teeth of which are engaged by a locking pawl 26. The operating shaftis also provided with fulcrum pins 27, for engagement with the spike orlever by which the shaft is turned or operated.

The side sheet 2 is provided with flanges 28 fitting under the end floorsheet 5 and outside hopper sheet 4;. And the end floor sheet 5 is inturn furnished with inner flanges 29, fitting inside the side sheet 2and outside hopper sheet 4. And the'outside hopper sheet 4 is furnishedwith flanges 30 on the outside of the end floor sheet 5 and inside theside sheet 2, thus making an exceedingly strong, and at-the same timevery simple and efficient construction and connection of the severalside sheets, end floor sheetsand outside hopper sheets of the dump carbody.

I claim 1. In an inside dump hopper car, the combinationwitli the centersills, upright side 1 sheets, inclined end floor sheets, lon itudinalinside hopper sheets and longitudinal outside hopper sheets, of doors,hinge brackets secured to the center sills under the inside hoppersheets, and an operating shaft, winddrums and doors, sai drums havingshouldered locking faces and a connecting link for eachdrumhaving acooperating shouldered locking face, substantially as specified.

3. In an inside dump hopper car, the combination with the center sills,upright side sheets, inclinedend floor sheets, longitudinal insidehopper sheets and longitudinal outside hopper sheets, of doors, hingebrackets secured to the center sills under the inside hopper sheets, andan operating shaft, winding drums thereon, supporting brackets for saidshaft secured under said outside hopper sheet, and connecting linksbetween said drums and doors, said upright side sheets being flangedunder said end floor sheets, substantially as specified.
